Question About Soil Characteristics vs. Explorer

A

Anonymous

Guest
Where I live, I have boring, very low mineralized neutral soil. I can run my Garretts practically wide open on sensitivity in this soil and get good substantial depth with all my VLF machines. It has been explained to me that the Sovereign and Explorer need some (?) mineralizations to maximum their operating potential. Without somw mineralizations, their depth capabilities is somewhat compromised....Comments...???
 
Just because Minelabs can handle bad ground better some people think they won't work as well in good ground, not true. FL. has very unmineralized soil and the Minelabs are performing great as can be read on any beach forum on the net.
I'm not sure how my soil compares to yours but my GTI I could run at 100% sens. and my Explorer I detect at just under. (28/32)
 
my ground here is bad enough but for overall I see ML takeing it all on world wide and doin it well I might add so Id say from all the finds out there it is the all purpose tone ID unit bar none <img src="/metal/html/biggrin.gif" border=0 width=15 height=15 alt=":D">
theres more but its too early <img src="/metal/html/wink.gif" border=0 width=15 height=15 alt=";)">
 
The rejection of neutral soil is based on pure ferrite. You never have that for any soil so all VLF detector see some minerals if the coil is on or close to the ground. If those minerals are near to the phase angle for pure ferrite then some detectors will default to a preset ground balance. However, this does no increase or decrease detection depth just becasu the phase is close to pure ferrite.
What you are not understanding is if you test a detector in the air then there is no ferrite. The detection depth can be much different than an air test depending on how a VLF is designed to respond to air. No ferrite indicates the coil is off the soil further than it should be. Some gold detector will not give a depth reading that is anywhere near as accurate in the air as for a target in the soil.
The Explorer does not need minerals for good detection depth and will always see some mineral even in what we call neutral soil. Recall that neutral soil would be pure ferrite so there is an offset in the design of ground rejection for real world soil. This detector does not need any mineral for maximum detection depth.
If you are not getting the depth you wnat then increase the audio gain to 8-10. Audio gain is preamp gain on most other detectors. At an audio gain of 10 you will get great depth. On a dime at least 10 to 12 inches depending on the soil and inclination of the dime in the soil.
Hope this helps,
Cody
